摘要
根据2005年1月(电场初运行时)和2007年1月(电厂运行两年后)对象山港国华宁海电厂热源排污口附近海域底栖生物的监测资料,对底栖生物种类组成、优势种、生物量、栖息密度、生物多样性和均匀度的变化分析表明:两次调查共鉴定到底栖生物5大类41种,软体动物和多毛类是构成该海域底栖生物的主要类群;电厂运行两年后的底栖生物种类、生物量平均值、生物多样性、底栖生物的栖息场和丰度都有减小的趋势,均匀度却有所上升。
Based on the data from investigation of the marine macrofauna near guohuaninghai electric plant in the Xiangshan Bay in Jan. of 2005 and 2007, the species composition,biomass,dominant species,density,diversity index,evenness were analyzed. The resuhs showed that total 41 species of zooplankton were identified. Mollusk and polychaeta were the main communities. Species composition,biomass,dominant species,density and biodiversity were on the decline, while evenness was on the rise.
